Specification of Letters Patent.

Patented Nov, 16, 1909.

To all whom it may concern:

Be it known that I, SIMON SCHLANGEN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Filling Apparatus for Liquids, of which the following is a specification.

The invention relates more especially to an apparatus by means of which barre-ls, half barrels, kegs, and similar packages, can be filled with liquid, such as beer, under pressure, with the package sealed and filled,

while sealed, under an equalized pressure between the supply tank for the liquid and the to-be filled package; and has for its objects to improve the construction and operation of the sealing head and the seal carried thereby for sealing the package prior to equalizing the pressure between the package and the supply tank for the liquid before discharging liquid into the package; to con trol the flow of air and liquid, between the to-be filled package and the supply tank for the liquid, through the medium of a valve automatically operated with the descent and ascent of the filling tube in opening and closing the valve; to furnish a sealing or closing head having therein a passage in connnunication with a controlling valve having a rod or stem actuated by the descent and ascent of the filling tube to open. and close the valve; to operate a controlling valve, mounted on the sealing or closing head, by means of a stem having thereon cam flanges engaged by a wheel or disk carried by the filling tube, for the wheel to engage the cam flanges and automatically turn the valve stem to open and close the valve; to furnish a controlling valve mounted on the sealing or closing head and having ports, one port in communication with a tube leading to the supply tank and delivering any o verfiow at liquid from the to-be filled package to the supply tank, and the other port in communication with a tube leading to the supply tank for the passage of air or other medium under pressure between the to-be tilled package and the supply tank for liquid; to improve the. construction and operation of the filling tube, as regards the valves controlling the discharge of the liquid from the filling tube; to improve the head carrying the filling tube; to improve the valve controlling the discharge of the liquid l at the lower end of the filling tube; to enable the filling tube, when raised, to close the passage in the sealing or closing head and prevent further outflow of liquid; to open the discharge valve at the lower end of the filling tube after the filling tube is fully entered into the package; to enable a piston and piston rod to open the discharge valve at the end of the filling tube when the filling tube is fully entered into the to-be filled package; to furnish a main controlling valve by means of which the flow of liquid into the to-be filled package from the supply tank for the liquid and the flow of air, or other medium under pressure, from the supply tank into the to-be filled package are regulated and controlled; to improve the construction and operation of the main controlling valve for the liquid and air, or other medium under pressure; and to improve generally the construction and operation of the several parts and mechanisms which enter into the construction of the apparatus as a whole.

The invention consists in the features of construction and combinations of parts hereinafter described and claimed.

The apparatus, in the construction shown, has, at each end, a front standard or leg 1, with a'flange 2 at the lower end by means the standard or leg can be secured to the floor, or other support, in the room where the apparatus is located; and, at each end and in line with the front standard or leg 1, is a rear standard or leg 3, having, at its lower end, a flange corresponding to the flange 2 and by means of which the rear standard or leg is secured to the floor, or other support, like the front standard or leg 1 is secured. A curved cross piece 4, having, at each end, a flange 5, is secured to the upper ends of the standards or legs 1 and 3, as shown in Fig. 2, and the cross pieces 41, in connection with the standards 1 and 3, at each end, furnish a support or frame on which is mounted the supply tank 6 for the liquid. At each end of the tank 6 is a flange 7, and a companion flange 8 is formed on a head 9 for closing each end of the tank. The flange 7 has thereon a plurality of ears 10, and the flange 8 has thereon a plurality of companion ears 11, and each pair of ears 10 carries a pivot or pin 12 on. which is mounted a swinging bolt or stem 18, having at the end a hand nut 14 which bears against a washer 15 on each stem or bolt 13, so that by turning the hand nut the flanges 7 and 8 can be made to abut closely for closing each end of a tank 6 by a head 9, it being understood that between the flanges a suitable packing is inserted, so as to make a tight joint for each end of the tank.

A plate 16 is attached by suitable bolts, or otherwise, to the upper end of each front standard or leg 1, and each plate has, at its upper end, a socket or bearing 17 in which is entered the end of a cross rod 18, and the cross rod is firmly secured in each socket or bearing 17 by clamping or looking nuts 19 engaging the end faces of the socket or bearing, as shown in Fig. 1. A cross rod 20 is entered into a lower socket on the plate 16 at the rear of each standard or leg 1, and this rod is fixedly held in place in the sockets or bearings at its ends by clamping or locking nuts 21, which bear against the end face of the socket or bearing. The rods 18 and 20 furnish a support for the several frames carrying the swinging frame and the frame supporting the sealing head and filling tube.

The apparatus, shown in Fig. 1, has three filling appliances, so that three packages can be filled from the same supply tank, but each filling apparatus is of the same construction and a description of the various parts for one filling apparatus applies equally as well to each filling apparatus shown in Fig. 1.

The frame supporting the filling apparatus consists of two side frames or supports. Each side frame or support has an upper and lower bracket or arm 22, each connected by a flange 23 and suitable bolts to the wall of the supply tank 6, as shown in Fig. 2. An upright piece or bar 2t connects the brackets or arms and 23, and a downwardly inclined or diagonal piece or bar 25 extends from the upper end of the piece or bar 2%, and at its forward end is joined to an upi'vardly inclined or diagonal bar 26, extending from the lower end of the upright piece or bar 24, so that the brackets or arms 22 and 23 and the pieces or bars 2%., 25 and 26 form an integral whole supported from the wall of the filling tank and constitute side frames, between which the swinging frame, supporting the motor cylinder and the sealing head and filling tube, is mounted. Each side frame, at the uncture of the pieces or bars 2% and 26 has a head or boss 27, with a depending ear-28, and integral with the lower bracket or arm 22, and this head or boss has a hole 29 for the passage of the supporting rod or tube 20, so that the rod or tube 20 furnishes a lower supportfor each side frame. Each side frame, at the juncture of the pieces or bars 2%, and 25 and in line with the upper bracket or arm 22, has a head or boss 30, with a hole 31 for the passage of the rod or tube 18, so that the rod or tube forms an upper support for each side. frame. Each side frame, at the juncture of the pieces or bars and 26, has a head or boss 32, with a hole 33, to receive the trunnion or journal pin at the end of the sidewise rocking member of the supporting frame for the motor cylinder and the sealing l cad and filling tube.

The supporting frame for the motor cylinder and the sealing head and filling tube consists of an outer ring member 3st of an oval shape, as shown in Fig. 1%, and at each end of the outer member Iii-l, is a depending car 35 projecting out from which is a trunnion or bearing pin 36, of a f shape, as shown, which enters the hole 33 in the side frame, so that the outer member is free to rock sidewise on the knife edge trunnions or bearing pins, he outer member 34: of the frame encircles the inner member of the frame, which member-is supported in bearings 37 on the outer member, as shown in l 9. The inner member of the frame consists of a plate 38 hating a rib or flange 39, and ha ing, at each e d, an ear l0, with a hole 41 for the attachment of the vertical side rods of thesn-inging frame. Each side of the main body or plate of the inner mcmber of the supporting frame or table has a boss 42 extending out from which is it ournal pin or trunnion l3, which enters the bearings 37. so that the inner member of the supporting frame or table is free to rock endwise on the journal pins or trunnions, thus giving the supporting frame or table a sidewise rock from the outer frame and an endwise rock from the inner frame, by means of waich the sealing head and the bunghole.

filling tube can be made to properly center with the bunghole of the package, so as to insure the perfect sealing of the package at the bnnghole and a clear passage for the filling tube into the package through the An annular will or rim depends centrally from the under side of the main body or plate 38 of the inner member of the supporting frame or table, and this rim or wall std surrounds a chamber l5, having a countersink or concave wall or face an at the upper end, with a hole a? leading through the main body or plate 38, as shown in Fig. 10. The chamber l5 has entered thereinto a packing ring atS contacted by a washer -9, against which a follower ring nut 50 acts to compress the packing ring. The packing ring, washer and follower or ring nut each have a hole 51 in line with the hole t? for the passage of the piston rod of the piston of the motor cylinder.

The piston rod passes through th holes 47 and 51, and, at its upper end, has secured thereto a piston of any suitable construction, which piston reciprocates in a cylinder 5%, closed at the top by a cap or cover cured in place by an angle iron band it; and suitable bolts, by means of which the angle iron is secured to the wall of the cylinder and to the cap or cover, as shown in Fig. 1 The lower end of the cylinder is entered into an annular rim having a lateral flange by means of which and suitable bolts, or otherwise, the rim is attached to the upper face of the main body or plate 38 of the inner member of the supporting frame or table. The main body or plate 38 of the inner member of the supporting frame or table has therethrough a hole, 59 which opens into the interior of the cylinder G l, so as to admit air, or other niecinm under pressure, into the cylinder below the piston and discharge air, or other medium under pressure, from the cylinder below the piston in reciprocating the piston.

The inner member of the smpporting frame or table has attached thereto a pair of side rods (30, with. the upper end of each rod entering into a hole at of the inner member of the frame or table and secured in place by an under locking nut or flange 61 and an upper locking nut (32, so that each rod 60 is fixedly attached at its upper end. The lower end of each side rod 60 is entered into and through a hole (33 in an ear 6% of a cross head or plate 65-, which, as shown, has acentral raised portion or face (it; furnishing a stop to limit the descent of the filling head and the filling tube: and each rod is securely held in place by an upper j am nut 67 and a lower jam nut (38. which nuts abut against the top and bottom face respectively of each car 64 of the cross plate or head 65, as shown in The cross plate or head (")5 has, at each end, and inside of the vertical tie or supporting rod or tube 60, a hole 69, and each hole 69 has passing therethrough a rod 70, and each rod 70 passes through an eye, formed by half rings 71 shown in Fig. 13, one half eye 71 at each end of a cross bar 72 and one half eye 71 at each end of a cross bar 7 3, the two cross bars 72 and 73 forming a cross head 74 consisting of two members, and the two cross bars or members 72 and 73 of the cross head are secured together by belts or screws 7 5, passing through lugs or bosses 7 0 on each cross bar or member, as shown in F 12 and 11%. The cross head 7 at, as a whole, is fixedly attached to the side rods 70, by set screws or bolts 77 each passing through a boss 7 8 on the cr is bar or member 72 at each end thereof, for the end of each set screw or bolt 77 to engage the side rod 70, so that the side rods 70 and the cross head 71 will move as one. The upper end of each cross rod 70 has attached thereto a ring or band 79 encircling the motor cylinder and the ring or band 79 is formed of two half rings 80 and 81, each half ring, at each end, having an car 82, through which ears a tightening bolt 83 passes, by means of which the band 79 is fixedly attached to the upper end of the two side rods, for the side rods and band to move together, and the band 79 also serves as an additional weight to the weight of the side rods and cross heads for self-lowering the sealing or closing head in sealing a package.

The lower end of each side rod 70 enters a hole 84. in an car 85 on a cross bar or head constituting the sealing or closing head and having, on one side, a projecting member 86 and on the opposite side a projecting member 87, ach member terminating in an ear or end 85, and each side rod 70, at its lower end, passes through the ear or end 85 of each member and is securely held in place by a jam nut 88, engaging the upper face of the end 85, and a lock or tightening nut 89, engaging the under face of the end 85, so as to hold the sealing or closing head in position on the lower ends of the sliding rods 70 for the sealing or closing head to move up and down with the rods. A web or tin 90 connects each side member 86 and 87 with a center 91, which center has, in its under side, a central hole 92, in which is entered a sleeve having, adjacent to its lower end, a shoulder 941- and terminating in a tapered end 95, to facilitate entering the seal into the bunghole of the package. A space 96 is formed between the shoulder 94 and the under face of the center 91, and this space receives a sealing rin .)7, of india rubber, or other suitable material, which is located between the shoulder 94, and the under face of the center 91 and around the sleeve and has a tapered or conical exterior face for entering the bunghole of the package and sealing the package during the filling operation. The upper face of the center 91 of the cross head, has an upwardly extending annular rim or flange 98 inclosing a chamber 99, which receives a packing 100, compressed by a follower'or ring nut 101, threaded into the interior of the flange or rim, as shown in Fig. 5. The inner face of the sleeve 93 has inwardly projecting lugs or bearing points 102 furnishing a guide for the filling tube and maintaining the filling tube away from the inner face of the sleeve, so as to furnish a passage 103 between the exterior of the filling tube and the interior of the sleeve, as shown in Fig. 5, and this passage 103 opens into a passage 104 having, at one end, an opening 105 extending through the side arm or member 87 of the cross head.

A rim or neck 106, at the lower end of a valve shell or casing 107, is entered into the opening or hole 105 of the arm 87 of the cross head at the lower end of the reciprocating rods 70, and the valve casing or shell 107, adjacent to its lower end, has a flange 108, by means of which and suitable bolts the valve shell or casing is attached to the arm 87 of the cross head. At the upper end of the shell or casing 107 is a cross wall 109 extending up from which is an annular rim or wall 110 inclosing a chamber 111, in which is located a packing ring 112 compressed, by a follower or ring nut 113 around the tubular stem 11 1 extending up from the end wall 115 of a controlling valve, so as to make a tight joint against leakage around the tubular valve stem. The shell or casing 107 has entered thereinto a tapered valve plug formed of the upper end wall 115 and a side wall 110 and inclosing a chamber 117, with a port 118 in the wall 116, furnishing communication with the chamber 117, which chamber, at its lower end, is in communica tion with the passage 104; at the opening 105, as shown in Fig. 5. The wall of the shell or casing 107 has a port or opening 119, in communication with a passage 120 in a neck or boss 121, and the wall of the shell or casing 107 has a port or opening 122, in communication with a passage 123 of a neck or boss 124,-, so that, by properly turning the valve plug, the port 118 of the plug can be brought into communication with the port 119 or the port 122, as may be required in opening and closing communication between either port 119 or 122 and the chamber 117 of the valve plug.

A tube 125 is entered at one end into the neck or boss 12 1, and its other end is connected by an elbow coupling 126 with a vertical pipe 127, the other end of which pipe 127 is connected by a coupling 128 with a hose or other conduit 129, and the hose or conduit 129 connected at its other end with a neck or boss 130 of a T coupling 131 having, opposite the neck or boss 130, a neck or boss 132; and, as shown, the wall of the T coupling 131 constitutes a shell or casing in which is located a valve plug 133, by means of which conununication can be shut ohf between the tank 6 and the T coupling, which is entered into the wall of the tank and has free communication with the interior of the tank 6, when the valve plug 113 is properly turned. A tube 134 is entered at one end into the neck or boss 121 and its other end is connected by an elbow coupling 135 with a short tube 136, entered into a coupling 137, by which the shell or casing 138 of a check valve is attached, and the check valve is attached, by a coupling 137, to the casing 139 of a sight glass 140, which frame or casing has a neck or boss 141 into which is entered the lower end of a vertical tube or pipe 142, the upper end of which is connected by a coupling 143 with a hose or other conduit 144, and the other end of the hose or con duit 144 is connected to the neck or boss 132 of the T coupling, so as to establish communication with the interior of the tank 6, when the valve plug 133 is properly turned. it will be seen that when the valve plug 133 is turned, so as to establish communication with the T coupling 131 and the interior of the tank, and when the valve plug on the arm 87 of the cross head is turned to bring the port 118 into communication with the port 12;, communication is established, between the interior of the tank 6 and the chamber 117 of the valve plug, so that air, or other medium under pressure, is free to flow from the tank into the chamber 117 and enter the passage 104 and discharge through the passage or channel 103, when the sealing head has closed the bunghole of the package, for the air, or other medium under pressure, to enter the package and equalize the pressure between the tank and the package; and with the port 118 in communication with the port or opening 122, the port or opening 120 is closed against communication with the chamber 117 of the valve plug, as shown in 18. The turning of the valve plug into the position shown in Fig. 17 brings the port 118 into communication with the port 119, establishing communication between the chamber 117 of the valve plug and the passage 120, so that, with the sealing head closingthe bunghole of the package, communication is established between the interior of the package and the sight glass through the passage or channel 103, passage 104, chamber 117 of the valve plug, port 118, port or opening 119, passage 120 and the connection between the passage 120 and the sight glass and with communication established with the sight glass, communication is also established between the interior of the package and the interior of the tank 6, through the tube or pipe 142 and hose or conduit 144 and the T coupling 131, so that pressure within the to-be filled package, as the liquid fills the package, will be returned to the filling or supply tank 6 and add the pressure within the package to the pressure in the tank, thereby maintaining the proper pressure within the package, and as the package becomes filled the beer or other liquid will tiow into the sight glass following the pressure, and when the beer or other liquid shows in the sight glass 140, such showing indicates that the package is filled. Any overflow that might occur, by a continued discharge of the liquid into the package will pass through the sight glass and into the tube or pipe 142 to the height of the liquid in the tank, to be discharged into the next to-be filled package with the opening of the ports 118 and 119, thus preventing any waste of the liquid by reason of overflow.

A valve rod or stem 145 is entered at its lower end into the tubular stem 114 of the valve plug in the casing or shell 107 and is connected to the tubular stem 114 by a cross pin 146 or otherwise. The stem 145 passes upwardly through a hole 147 in the cross head 65, and the cross head 65, in its upper portion, has formed therein an annular reess 148 into which is entered a disk or circular plate 149 at the lower end of a tube 150; and the disk or plate 149 has an annular shoulder 151 forming, with the disk or plate, a depression which receives a ring 152 attached to the cross head 65 by suitable bolts or screws 153, or otherwise, so that the disk or plate 149 and the tube 150 are free to turn. The tube 150 has an inwardly project-ing pin or stud 154 which engages a longitudinal slot 155 in the valve stem 145, locking the tube 150 to the stem 145, so that the turning of the tube will turn the stem and at the same time the stem is free to move up and down, by reason of the slot 155, with the raising and lowering of the sealing or closing head. The exterior of the tube 150 has a lower cam plate or flange 1.56 and an upper cam plate or flange 157, which plates are attached to the tube by suitable screws 158, or otherwise, and by means of which plates the tube 150 can be turned to turn the valve stem 145, for the valve stem to turn the valve plug within the shell or casing 107 and open and close communication through the port of the valve plug with the ports of the shell or casing. A sleeve 159 is attached to the valve stem 145 below its upper end by means of suitable bolts or screws 60, or otherwise, and this sleeve 159, on its eX terior, has a cam flange or plate 161 by means of which the valve stem 145 can also be turned, turning the valve plug in the shell or casing 107 to open and close communication between the port 118 of the valve plug and the port 119 and 122 of the shell or casing.

The valve stem 1 15 is turned 01 rocked, through the cam plates 156 and 157 and 159, by means of contact wheels or rollers 162 and 163, having an up and down movement coincident with the up and down movement ofthe filling tube. Each roller 162 and 163 has, in its inner face, a countersink 1641, which receives a flange 165 on the end of a journal pin 166, and each journal pin is screw threaded at its outer end and has entered thereonto a nut 167, by means of which the journal pin is fixedly held in an ear 168, which ears 168 project out from a plate 169, and the plate 169 has projecting ears 170, by means of which and suitable bolts 171 the plate is attached to ears 172 on the neck 17 3 of a shell or casing 17 1, so that the rollers 162 and 168 will travel up and down with the shell or casing 174, and in so traveling will contact the cam plates 156, 157 and 161 and turn or rock the valve stem 145 in opposite directions.

The shell or casing 174, at its upper end, has a flange 175, and is connected to a cross bar or head 176 by means of suitable lag bolts or screws 177, and, as shown, a packing 178 is inserted between the flange 175 and a facing 179 on the cross bar or head 176, so asto make a tight joint, between the shell or casing 17% and the cross bar or head 176, to prevent leakage. The cross bar or head 176, at each end, has a slot or hole 180, through which the side rods pass, and the cross bar or head .17 6, at one end, has a hole 181 for the passage of the valve stem 145, so that the side rods 70 and the valve stem 145 are free to slide through the cross head or bar 176 in the up and down movement of the sealing or closing head and the filling tube. The cross bar or head 176 has upwardly extending therefrom a neck or boss 182, with a hole 183 into which enters the lower end of the piston rod 5-2, so that the cross head or bar is connected with the piston rod.

The shell or casing 174:, on one side, has a rim or *all 184 which surrounds a port or hole 185 in the wall of the shell or casing 171- and furnishes communication with the chamber 186 of the shell or casing, for admitting liquid to the chamber 186. An inner wall 187 is located within the shell or casing 17th, and its upper end has thereon a valve seat or seating face 188, with which a seating face 189 on a ring 190 coacts. The ring 190 is threaded onto the exterior of a neck or rim 191, extending up from a top wall 192 of a piston valve, having a side wall 193 and free to reciprocate in a pasage 191- within the neck 17 3 of the shell or casing 1761, so that the seating faces 188 and 189 can act and open and close communication between the chamber 186 and the chamber of the piston valve, for admitting liquid to the chamber of the piston valve.

The lower" end of the piston valve, in the construction shown, has a flange or rim 195 which is cut away on one side so as to furnish an opening 196 in order that the piston valve may pass the retaining ring 152 and have the under face of the flange or rim 192 contact the upper face of the center 66 of the cross head 65, when the filling tube is lowered. The chamber 197 of the piston valve is open to communication with the chamber 186, by means of ports 198 formed in the wall 193 of the piston valve, as shown in Figs. 5 and 6, and communication is established when the seating face 189 is out of contact with the seating face 188, as shown in Fig. :3, and communication is closed, between the chambers 186 and 197, when the seating faces 188 and 189 are in contact as shown in Fig. 6. The lower end of the chamber 197 of the piston valve has a mouth or opening 199, within an inwardly projecting bead or flange 200 on the interior of the wall 193 of the piston valve, as shown in Figs. 5 and 6; and below the rib flange 200 is an opening 201, terminating in a shrnilder 202, into which opening and abutting against the shoulder 202 is entered the upper end of the filling tube 203, so

that the filling tube is connected with the piston vi lve, and, when the piston valve is opened for its chamber 197 to be in communication with-the chamber 186, liquid can flow into the filling tube, and when the pis ton valve is closed against communication between the chambers 186 and 197, the flow of liquid into the filling tube 203 is shut ott'. The lower end of the filling tube receives a sleeve 201 having a side wall 205 and a top wall 206; and encircling the sleeve 20%! is a ring 207 having an inclined upper face 208, as shown, adapted to engage the inclined end faces of the projections 102, when the sleeve 201 is entered into the lower end of the filling tube, as shown in Fig. 25. The sleeve 20t has a chamber 209 closed at its lower end by a plug 210, as shown in Figs. 5 and 6. A ring nut 211 is threaded onto the exterior of the annular side wall 205 at its lower end, and between the ring nut 211 and the ring 207 is located a packing ring 212, which is compressed and seated against the inner face of the sleeve 93, when the lower end of the filling tube is within the sleeve 93, as shown in Fig. 25, and in this condition the sleeve and the packing form a controlling valve at the lower or discharge end of the filling tube. The end wall 206 has therein a hole 213, through which passes a rod or stem 214:, at the lower end of which is a nut or head 215; and between the nut or head 215 and the face of the end wall 206 around the lower end of the stem 211 is a coil spring 216, which serves to hold the sleeve 204, ring 207, and packing ring 212 in position for closing the passage around the lower end of the sleeve 93 and of the filling tube against the discharge of liquid. The upper end of the rod or stem 21%, connected by a coupling nut 217, with the lower end of the piston rod or stem so that the two rods or stems move together and with r -1 cross head or bar 176 which has a recess 218 in which the coupling nut 217 is entered.

The flange or rim 195, on its front and rear side, has a projecting ear 219, in each of which is secured the lower end of a rod 220, and the upper end of each rod 220 passes through an car 221, on the front and rear sides of the flange 175 of the shell or casing 174, so that each rod is free to slide up and down in its ear 221, and a coil spring 222 encircles each rod 220 between each pair of ears 219 and 221, which coil springs serve to return the piston valve, from its raised position to its closed position, and to hold the seating faces 188 and 189 in abutting relation, thereby shutting off communication between the chambers 186 and 197 and preventing the inflow of liquid into the filling tube.

A swiveling coupling 223, on the end of a hose or conduit 224., connects the hose or conduit with the rim or flange 18% of the shell or casing N t-around the piston valve of the filling tube; and the other end of the hose or conduit is connect-ed by a swiveling coupling 225 with the rim or flange 226 of a goose neck 22?, having a passage 228 and formed with, or suitably connected to a shell or casing 229, which shell or casing has a flange 230 with a neck 2 1 extending from the flange, the neck having a passage which continues through the wall of the shell or casing 229 as does also the passage 228, and the neck 231 is entered into the under side of the filling or supply tank 6, so as to be in communication with the interior of the tank. The shell or casing 229 has a chamber in which -ntered a valve plug 233, which, as shown, has a chamber with ports opposite each other in the wall of the valve plug, as shown in Figs. 19 and 20. The small end of the valve plug has, extending out from the center, a stem 236 on to which is threaded a nut 237, which bears against a washer 238 and forces the washer 238 in close contact with the end face of a neck or boss 239 on the shell or casing 229 of the valve, so as to close the valve at the small end of the valve plug as usual. The large end of the valve plug 233 has. projecting out therefrom at the center, a rectangular or square shank or stem 240 for a handle 241 by means of which the valve plug 233 can be turned for the ports 235 to be in line with the passages 228 and 232, or the valve plug can be turned so as to close the passages 228 and 232, as shown in Figs. 19 and 20. The turning of the valve to discharge from the valve.

plug 233, to furnish communication between the passages 22S and allows the liquid to flow from the tank and pass through the hose or conduit 224: and into the chamber 186 of the shell or casing 174 of the head of the filling tube, so that, with the piston valve on the upper end of the filling tube open, liquid from the tank can fiow through the filling tube and with the valve at the lower end of the filling tube open, the liquid can discharge into the package. The liquid will continue to tlow from the tank into the hose or conduit 224, so long as the valve plug 233 is in position to furnish communication through the ports 235 with the passages 228 and 232; and with the turning of the valve plug 233 for the ports to be out of line with the passages 228 and 232, the outflow of liquid from the filling or supply tank 6 into the hose or conduit 224 is shut off or stopped.

A. valve for controlling the air, or other medium under pressure, to operate the piston 53 in the cylinder 5% is employed. The valve shown has a shell or casing with a tapered chamber 213, and around the exterior of the shell or casing is located a plurality of necks or bosses, four being required in the construction and arrangement of the valve shown. A boss or neck 21 having a passage admits air, or other medium under pressure, to pass through the 'al've: and a boss 246, with a passage 24?. allows air. or other medium under pressure, 1 A boss or neck 243, having a passage 249, furnishes a connection for one of the supply pipes leading to the motor cylinder; and a boss 250., with a passage 251, furnishes a connection for the other supply pipe leading to the motor cvlinder. The tapered chamber 243 of the slicll or casing 2&2 has located therein a tapered valve plug 252, and this plug has, in line with the several passages or ports 2%, 249 and 251, a passage having at one end a port 25s and at the other end. a port 255, and a passage 256, having at one end a port 257 and at the other cut a port 258, with a wall or partition 259 between the passages and 256, as shown 1n Fi. s. 22 and 23: The valve plug when turned into the position shown in Fi 22. allows air, or other medium under pr, I. to directly flow, through the passage 2&5. port 25%, passage and port into the passage 249, to be delivered, in the arrange ment shown, to the upper end of the motor cylinder, and at the same time the passage 251 is in communication with the port 257, passage 256. and port 258, for air, or other medium under pressure, to discharge from below the piston in the motor cylinder, so that when the air, or other medium under pressure, enters the cylinder 54 above the piston and acts to force the piston downwardly, the air, or other medium under pressure, below the piston, discharges at the port or passage 247 into the atmosphere, or otherwise. The turning of the valve plug into the position shown in Fig. 28 reverses the operation, as with the valve plug 252 turned as shown in Fig. 23, the inlet. passage 2+t5 is in connnunication with the port 257, passage 256 and port 258, for air, or other medium under pressure, to enter the passage 251 and be dischar ed into the cylinder 5% below the piston 58, for the air, or other medium under pressure, to act and raise the piston, and with the admission of air, or other medium under pressure, to the under side of the piston, the air, or other medium under pressure, above the piston, discharges, entering the passage 24.9, and, through the ports and passage 254-, 258 and 2 3, discharging at the passage 247 into the it will thus be atmosphere, or otherwise. seen that by means of a single valve of the construction shown and described, air, or other medium under pressure, can be admitted to or discharged from either end of the cylinder 54t-to reciprocate the piston in such cylinder.

The valve plug 252, at its larger end, has a pin or stop 260, arranged. to engage an upper and lower lug 261 and limit the turning of the valve plug in either direction and at the proper point for the ports and pas sages to be in colmnunieation. The smaller end of the valve plug 252 has projecting out theretron'i a screw threaded stem 262 onto which is entered a nut 263 by m ans of which the valve plug is held in the shell or casing, so as to prt ent leakage of the valve. The valve plug 252, at the center of the larger end, has a rectangular or square stem 264 for the attachment of a handle 265 by means of which the valve plug can be turned as required for opening the ports in admitting air to and discharging air from the upper and lower ends of the motor cylinder.

A pipe or tube 266 has its lower end entered into the neck or boss 2 l8, and this pipe 266 extends upwardly and is connected, at its upper end, by an elbow coupling 267, with a horizontal pipe or tube 268 formed in two parts or sections connected together by a T coupling 269, one neck or boss of which coupling has entered thereinto a pet or release cock 270 for venting purposes when required. The other end of the pipe or tube 268 is connected by an elbow coupling 270 with a short tube 272 entered into a hole 273 at the center of the cap 55 of the cylinder 541., as shown in Fig. 3. The pipe 266, with the valve plug turned as in 22, allows air, or other medium under pressure, to discl'iarge into the upper end oi the cylinder 54: above the piston 58, for the air, or other medium under pressure, to act and force thepiston downward; and with the forcing of the piston upwardly the pipe 266 allows the air, with the valve plug turned as in Fig. to discharge at the passage 247 into the air, or elsewhere.

A short pipe or connection 27st is entered at one end into the neck or boss 250, and its other end is connected by an elbow 275 with a horizontal pipe 276, the other end of which is connected by an elbow 277 with a short pipe or connection 278, entered into the hole 59 in the inn-er plate 58 of the supporting frame or table, for the admitted air to enter the motor cylinder 5% below the piston 53 and move the piston upward; and with the moving of the piston 53 downwardly the air, or other medium under pressure, below the piston, flows back through the pipe or tube 276 and is discharged at the passage 2-l7 into the atmosphere, or elsewhere. The air, or other medium under pressure, admitted to the pipe 276 when the valve plug is turned as in Fig. 28, and the air, or other medium, is discharged through the pipe 276 with the valve plug turned as in Fig. 22.

A hose or conduit 279 is connected at one end by a coupling 280 with the neck or boss 244, and at the other end is connected by a coupling 281 with a neck or boss 282 on a supply pipe 283 for air, or other medium under pressure; and the pipe 283, in the arrangement shown, is supported in slots or recesses 28-.l formed in ears or wings 285 on the bosses or bearings 30 of each side frame and on the sockets or sleeves 17 of the plates 16 on the front standards, as shown in Figs. 1 and The supply pipe for air, or other medium under pressure, is connected with the top of the supply or filling tank, in which the medium is under pressure, so as to maintain a regulated pressure in the supply pipe 283, and the air, or medium under pressure, is conducted under the regulated pressure, through the hose 279, into the passage 21:5, to be transmitted through the passages 253 and ports 25% and 255, and the passage 256 and the ports 257 and 258, to discharge by the tube or pipe 266 into the upper end of the cylinder at, or to discharge by the pipe 276, into the lower end of such cylinder for supplying air, or other medium under pressure, to the cylinder above and below the piston :tor the air, or other medium under pressure, to acton the piston 53 and lower and raise the piston.

, A pin or stud 286 projects outwardly from each rod or tube 60, and enters a slot 287 in a connecting bar or link 288, the other end of which bar or link is connected to a pin or pivot 28%) on the car 28 of each side frame and the pins 286 in connection with the slotted bars or links 288 limit the rearward swing of the motor cylinder and frame carrying the sealing head and the filling tube when the filling apparatus self swings rearward to clear the filling package and permit the bung or stopper to be inserted and driven or forced tightly into place to close the filled package.

The construction shown has a plurality of bands 200 extending partly around the filling or supply tank 6, and connected at their ends with the cross rod 18, which bands serve to furnish an additional support for the cross rod. The filling or supply tank (3, at one end on the under side, in the arrangement shown, has entered thereinto a bushing 291, connected with which is a controlling valve 292, having one end of a supply hose 293 connected therewith, which supply hose leads from a suitable source of supply for the liquid under pressure and the source of supply for the liquid, preferably, should be higher than the center longitudinally of the filling tank, so that when the valve 292 is open the liquid can flow by gravity from the source of supply into the filling tank, filling the tank half full, aoproximately, leaving a space above the liquid in the tank for compressing air, or other medium under pressure.

The construction shown has, at the front of the filling or supply tank 6, a sight glass 29% with a connection at its lower end, for the bottom of the filling or supply tank, and a connection 296 at the upper end, for the top of the filling or supply tank, by means of which sight glass the operator can determine the height of the liquid in the filling or supply tank.

A pressure indicating 297 is connected. with the pipe 283 for indicating the pressure in the pipe and in the tank. The pipe 283, in the arrangement shown, has a T coupling 298, and a pipe or hose 299 is connected at one end with the T coupling and at the other end with a bushing 300, entered into the wall of the filling or supply tank 6, so as to supply pressure from the interior of the tank above the liquid to the supply pipe for use in the motor or power cylinders. The air, or other medium under pressure in the tank, in the event of an eX- cess of pressure, in the arrangement shown, is vented or escapes into the pipe 233 by the hose or conduit 299, and from the pipe 283 the excess of pressure passes into a hose 301, leading from the pipe 283 to a reservoir or other place of use, which hose or conduit 301 is attached to a reducing valve 302 at one end of the pipe 283, the other end of the pipe being closed, and, if desired a relief valve can be connected with the top of the tank to escape an excess of pressure.

A support for a barrel, or other package, is provided for each filling apparatus, and such support is located underneath each apparatus. The support shown consists of bearing wheels 303 mounted on a tilting frame formed of side pieces orarms 304C and a foot bar or lever 305 between the side pieces or arms and by means of which the tilting frame can be raised and lowered, for the upward or rising movement to discharge the filled package. The tilting frame, having the rollers 303, coacts with rollers 306 mounted on a supporting rod 30'? held in position by brackets or'legs 30S attached to the floor, or other support on which the apparatus as a whole is placed, and, as shown, the rod 307, at each end, is supported in a plate 309 attached by bolts, or otherwise, to the inner face of each front standard or upright 1 of the main frame. The support for the barrel, or other package, having the rollers and tilting frame and the fixed rollers mounted on a supporting rod, is of the usual and well known form of construction for such sup port, and is, therefore, not specifically illustrated nor described.

It has been found in practice that the hose or conduit connecting a reciprocating filling tube with a stationary supply tank is liable to and does become twisted or kinked, through the rising and falling movement of the reciprocating filling tube, preventing the free flow of beer or liquid from the supply tank into the filling tube. This kinking or twisting is overcome by connecting the supply hose or conduit with the tank and with the filling tube by means of the swiveling couplings 223 and 225 which allow the hose or conduit to maintain a perfectly operative condition, without kinks or twists irrespective of the position of the filling head and the filling tube. Each swiveling coupling 223 and 225, in the construction shown, consists of a gooseneck 310 having, at the inner end, a flange 311 which enters a channel or open recess 312 formed in the wall 18%: of the filling head or the end wall 226 on the discharge valve of the tank; and in this cham her 312 is located a packing ring 313 of rubber or other suitable material, which is compressed in the chamber or channel 312 by a gland 31st and suitable tightening belts or screws 315 or otherwise. The packing ring or gasket should be compressed sufficiently to prevent leakage at the joint, and, at the same time, permit the coupling to turn with the reciprocating movements of the filling tube and maintain the hose or conduit free of kinks or twists, leaving a clear passage for supplying beer or other liquid from the tank to the filling head to enter the filling tube when the piston valve is opened, as already described.

The operation will be understood from the foregoing description, but briefly is as follows: A barrel, or other package to be filled, is placed on a support thereforbeneath the filling apparatus, for its bunghole to be on the upper side and approximately in line with the filling tube, so that with the descent of the sealing or closing head and the filling tube the seal will enter the bung-
